To all whom it may concern:

Be it known that I, ALFRED ARTHUR Gon- FREY, engineer, of The Linoleum Manufacturing Company Limited, a subject of the King of Great Britain, residing at Staines, in the county of Middlesex, En land, have invented certain new and useful mprovements in the Manufacture of Linoleum, 4of which the following is: a s ecification.A l

The olbject o this invention is te obtain linoleum With a wood-like appearance. To do this, l. form coils of a thin ribbon made of linoleum material of two colors, and I introduce these coils edgewise to a pair of rolls-- that is, the axis of each coil is approximatelyT per endicular to the axes ofthe rolls. Pretlera ly the ribbon is formed of dark and light colored material, so that the one sidegof the ribbon is darker than the other. This may be done by feeding the material from two, ho per-mouths close to the nip of a pair of rol s or from a single ho per divided into two compartments by a t iin plate extending down close to the mouth. The sheet so formed may be cut by a series of knives into a number of ribbons, or the .sheet may be rolled up into a roll, which is then cut up into coils, the cuts beingpcr )endicular-to the axis of the roll or incline thereto. The coils either formed of ribbons or cut from a roll are then rolled out thin, and the squeezing action. of the rolls causes the light and dark iiiatei inl io appear on' the face of the sheet so formed, and an excellent imitation of woodrrain is thus obtained.

lrel'erably the coils are formed on a maiidrel nliich can be withdrawn from them, and they are then flattened before passing through the rolls.

Figures 1 and 2 are a section and plan oi" a machine .for forming the coils. Figs. 3 and 4 are a section and lan of thc machine for rolling out the coi s. Figs. 5 and 6 are a cross-section ol' a coil formed on a mandrel before and after flattening.

o is a hopper with a central partition I), delivering light and. dark linoleum material to the nip of a pair di' rolls c, by which a sheet of linoleum dark on one side. and light on the other can be formed. This sheet is cut by a series of knives d beneath one of therolls c into a number of ribbonsjWhch-are coiled :into a number of coils e.

The coils are introduced edgewise between a' roll and guide-rolls y, by which they are fed to the Tpbetween the rollf and a similar roll 71 by ich they are anialgamated together and rolled out into a sheet7 as clearly shown in the drawings. The coils are of course packed as closely together as possible,

half-coils being used where necessary, somewhat superior effect is obtained by coiling the ribbons on. a mandrel, as shown in Fig. 5. After withdrawing the mandrel the coils are then squeezed flat, as shown in Fig. 6, before being introduced into the second machine, the squeezing action of which im- )arts the wood-like appearance to the finished sheet.

1. The process of manufacturing lincleum which consists in forming coils of a thin ribbon of linoleuin material introducing the coils edgewise to a pair of rolls and rolling out the coils substantially as described..

2. The process of manufacturing liiioleiiiii which consists in cutting up into ribbons a sheet formed of linolcuin material ol two colors formii'ig the ribbons into coils, introducing the coils edgcwise to a pair of rolls and rolling out the coils substantially as described.

8. The process of manufacturing liiioleum which consists iii cult-ting u') into ribbons a sheet formed ol liiioleuin material ol" two colors forming the ribbons into coils on a mandrel, \\'ithdra\viiig the mandrel from the coils, squeezing tliein llat,- introducing the coils odgewise to a. pair oi rolls and rolling out the coils substantially as described.

4. A she-et ol' liiioleiiiii composed of a iiiiiiiber ol coils consolidated together by rolls to which they are int rodiieed edgewise, tlie coils being i'oriiied ol' a tliin ribbon ol: liiioleulii material substantially as described.
